Cash withdrawal

Weekend of 29 November 2014 we went away and we had no cellphone reception. When we returned on the Monday afternoon, we received 2 sms's of account activity of an odd amount of +- R4970. We were under the impression it was a faulty transaction debited and then credited again by the bank and were going to the bank on Tuesday morning to sort it out. On Tuesday morning another withdrawal of the same amount came through via sms. We immediately arranged to go to Standard Bank as soon as the branch open. These were three withdrawals made in another country. Standard Bank ***** Division will only pay two of the three withdrawals, as they said we could respond to their ***** line. We didn't even know it was ***** until the third withdrawal!! After numerous communications, this was referred to higher management. After more communication, the agent at ***** Division said we could take this further, but they will only pay for two withdrawals, and if we refer the incident still further (ombuds man), they might decline to pay out any of the withdrawals. We accepted to take the two withdrawals, but my opinion: THEY STOLE ALMOST R5000 OF OUR MONEY AND GOT AWAY WITH IT!!
